Extreme cramps & small clots...help!!

Cate

So the month of dec I totally missed my period I was 11 days late (cycle 34 I believe) and I finally got my period but it’s been unbearable. I’ve never had such extreme cramping in my life, I had to call off work and buy muscle relaxers and I can’t even stand up straight. My first period day was heavy as f* and I went through one *big* pad and one super tampon, very red thick blood and day 2 was light but consisted of small blood clots and cramps I’d describe as knife stabbing. I was originally going to take a pregnancy test but with this “period” and pain I think I’m safe, but what do I do with this! I can’t get it to stop with regular pain meds and it seems to be lightening up completely (day 3) should I still test? Or is this all considered AF. Please let me know I’m sick with pain
